Ulster's Andrew Trimble and Roger Wilson have been called up to Joe Schmidt's Ireland squad for the November Guinness Series of internationals against Samoa, Australia and New Zealand.
But for Trimble especially, it provides an opportunity to kick start his international career. The omission of 50 times-capped Trimble from the original 34-strong squad named by new coach Schmidt raised eyebrows in Ulster rugby circles at the time, so most will view this as a case of justice being done, albeit belatedly.
And Wilson be will delighted, for when he rejoined Ulster from Northampton Saints in the summer of 2012, one of the reasons he gave was that he hoped it would boost his prospects of adding to his one international cap.
The inclusion of Trimble and Wilson raises Ulster's representation at the Ireland camp to 10, though their call-up will leave the province's head coach Mark Anscombe's squad even more thinly stretched for Saturday's PRO12 date with Scarlets in Llanelli.
As well as this weekend's trip to Parc y Scarlets, Muller will miss Ulster's home game against Edinburgh on November 22 and quite probably the game against Zebre in Parma on November 30 as well.
Worst case scenario, he could be an absentee when Ulster host Benetton Treviso in the first of two back-to-back Heineken Cup dates on December 7.
Rob Herring, who deputised for Ireland hooker Rory Best on Friday, suffered a dead leg against Cardiff, but although he was unable to train yesterday Ulster expect him to do so today.
